I was recently contacted by a reader who wanted to know more details about the Arca-Swiss p0 ball head for their potential use in the field. After speaking with them, I realized their application may require adjusting the base friction setting of the head, so I’d like to address that here. I will go step by step, with photos, on how to properly adjust the base friction setting on the Arca-Swiss p0 ball head to accommodate differing camera and optic weights to ensure the benefit of the elliptical ball head is maintained.
